Super Smoke — codelyoko

"I think I kept a little souvenir from my time with X.A.N.A."
–William refusing to pilot the Overboard in Cortex.

Super Smoke is William's special ability while on Lyoko after being possessed by XANA. Even after being freed from the program's control, due to being its slave for so long has caused the power to become an inherit part of his avatar.

William primarily uses it as a form of transportation and is fast enough able to even keep up with Aelita's angel wings. William can make his body collapse into black smoke and slither across the ground, at high speed. He seems to be completely invulnerable while in this form, even turning into smoke to avoid being injured. He can also move along other surfaces, and to enhance his jumps. He can also use it to create reins for the Black Manta. When he is devirtualized, his avatar dissipates with red vector lines and glowing red and black smoke.

With Super Smoke, he can turn his sword into smoke to return it to his hand. He can even throw a ball of smoke at a Lyoko Warrior engulfing them in smoke, capturing or knocking them down, and causing them to float above the ground, being guided by William's hand. Almost every time in Season 4, he uses it on Aelita in an attempt to throw her to the Digital Sea, although he only succeeded once in Distant Memory. In one instance, William was able to capture Yumi's fans and destroyed them in a puff of smoke, implying a capability to destroy weapons through this power.

William still possesses this ability in Code Lyoko Evolution as transportation on both Lyoko and the Cortex. He refers to it as a souvenir given to him by X.A.N.A.

Trivia

When using Super Smoke, William can even outrace Aelita's flying ability, and even go much faster than Ulrich's Super Sprint. He can also simulate Yumi's Telekinesis by levitating others.
In his short time prior to possession, William had not yet discovered his Lyoko ability, making this his only ability.
Super Smoke looks visually similar to the ghosts and polymorphic specters sent out by X.A.N.A on Earth.
In Evolution, he no longer yells it out like he used to when he was possessed by X.A.N.A.. Also, it now sparkles pale green pixels.
As it turns William into a non-physical form, he is unable to get hurt by Odd's laser arrows, as shown in Bragging Rights.
